In the second half of her show at the Hollywood Bowl on August 23, Broadway icon Kristin Chenoweth pulled a random audience member on stage to sing “For Good” from “Wicked.” Kristin had her part down pat, since she originated the role of Glinda on Broadway (and received a Tony nomination for it!), but what she didn’t realize was that her lucky fan, Sarah Horn, was actually a voice teacher who was ready to belt out the harmonies along with her. Magic ensues.
